The Aumax (98 Zone) showing is located at an elevation of approximately 2100 metres on a high ridge to the east of Cayoosh Creek, approximately 17 kilometres southwest of Lillooet.
The region is underlain by the Mississippian to Jurassic Bridge River Complex (Group), which is exposed along a broad, complex antiformal structure that plunges northwest. The group consists mainly of a thick sequence of bedded chert, chert argillite and argillite intercalated with altered basaltic flows (greenstone) and minor limestone. The greenstone is altered to listwanite (quartz- carbonate alteration) and flooded by pyrite. Most of the Bridge River Group exhibits pumpellyite- prehnite metamorphic grade. These have been intruded by Late Cretaceous to Paleogene granodioritic rocks.
Locally, a stockwork system of quartz veins, varying from 0.2 to 10 centimetres wide, is hosted by a shear zone in oxidized silica-listwanite altered greenstone. The zone strikes 160 degrees and dips 45 degrees west. Sulphide mineralization consists of small blebs of pyrite, arsenopyrite and possible tetrahedrite-tennantite with hematite and sericite alteration.
In 1999, a 1.0-metre channel sample (AR99+20) assayed 1.07 grams per tonne gold and 13.2 grams per tonne silver, while a 3.0-metre sample assayed 0.98 gram per tonne gold and 10.5 grams per tonne silver (Assessment Report 26236).
In 1991, the area was prospected as the Zee claim. During 1997 through 1999, the area was prospected as the Aumax claims. In 2004, Avino Silver & Gold Mines completed a program of rock and soil sampling. The following year three diamond drill holes, totalling 145.0 metres, were completed on the 97 zone with low assay results. During 2012 through 2016, Cresval Capital completed programs of rock and soil sampling and geological mapping.
